   This is really strange. Of course, I do not know all of the details about 
the un-publishable data. I see only two possibilities which could technically 
justify (although it would still be stupid IMHO) such a restriction :

(i) if the parameters are not just a few numbers derived from the database, 
but are a significant part of the database (like a list of all interatomic 
distances in the database)
(ii) if part of the study was directly paid by the CCDC

  But if neither (i) or (ii) are true, i.e. there are just a few parameters 
derived from a bought copy of the database, then this is a clear abuse of the 
data. What next ? Will we have to pay royalties every time a new structure is 
solved using some information mined from the database ???

  I understand the will to protect copying raw data from the database, but NOT 
derived information. This is the kind of abuse of intellectual property that 
is damaging to innovation and algorithms improvement, disregarding the 
commercial/open-source nature of the software. I'm not even sure it's legal 
to pretend 'owning' such parameters, unless we are in case (i) or (ii).
